As I understand, there is an orange exclamation mark or a warning light which is constantly flashing in the Dell 1320c printer. It seems like you have the wrong paper size selected in your printer. The paper in the printer tray and the paper size selected for the print is not the right one.

The PHD (print head device) or the transfer belt is nearing the end of usable life. When the orange exclamation mark is blinking, it usually means that the PHD or the transfer belt is past its end of life and will need to be replaced.
